Finally getting back to the PDA I bought on the fourth of July: a Zaurus. Anyway, I've tried personal organizer of the paper and leather kind, but they just didn't take. So now I'm reading up on the open source Zaurus OS (oz) and Opie. I've been able to install and run Apache with a PHP module and MySQL, and I'm planning on writing a little web app that allows me to take structured notes for DVD titles, books, and other info.
